Why ditch the polls?
We've all seen the human element in the NCAA committees. Of course, the one everyone's most familiar with is basketball, but every sport has a "basketball" committee, where human beings take the objective data, review it, crunch it, and then make subjective decisions. So I think generally the reason that it's a human committee now – rather than the combination of humans and computers – is just that it was a new day, a time for a fresh beginning, and we all are aware that the NCAA committees have worked so well, and our group just decided, 'Hey if it works for them, then it should work for us, too.' Even the BCS selection process is dominated by humans. I saw a piece the other day, I can't verify it, that the computers have never trumped the humans in the final BCS standings. Point is that decisions have been made by humans throughout the BCS era.
